This oil pipe hose runs from the VAN0S adjusting unit to the oil filter housing. At some point the rubber line shrinks or cracks and oil can weep out of the swedge fittings. The fittings at the banjo bolts can also leak so replacing the seals for each banjo fitting is strongly recommended.

Continental is the OEM supplier for the stock serpentine accessory belt on your M52TU or M54 engine. They are also the OEM for many other components on your entire car. This extensive kit covers many of the common wear items that should be changed any time the serpentine belt is being replaced. As these cars gain years and mileage the belt tensioners will also need to be replaced along with the actual belts. It won't do any good to replace the belt if the tensioners are worn. This kit will save you time and money over buying these pieces individually and you get OEM-quality over any 3rd party aftermarket brands.

Included in the accessory belt and tensioner kit is:
  • main drive belt, 11281706545
  • A/C belt, 11281437450
  • mechanical belt tensioner with pulley, 11281427252
  • A/C belt tensioner with pulley, 11287512758
  • deflection pulley, 11281748130
  • mounting bolts

This kit fits cars with the mechanical belt tensioner only. Generally this is all cars up to 2002 model year but you may want to double check your car and match the picture to the tensioner on your engine. The hydraulic tensioner has a miniature shock absorber on the belt tensioner. You can also tell early from late by the A/C belt. BMW changed the spec from a 5-rib belt up to 2002 to a 4-rib belt from 2003 onwards. This kit does not fit any M56 SULEV engines.

This item fits the following BMWs:
1999-2002 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable.

This is the sealing o-ring used for many oil cooler kits on various BMW models. They're also a prime source for oil leaks because the o-ring gets 'flat' or shrinks or becomes damaged. These are usually easy to change though which puts an end to annoying small oil leaks.

Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

This Oil Pressure Switch fits the following BMWs:
1985-1991 E30 318i, 318is, 325e, 325i, M3

The camshaft position sensor is essential for assisting the engine DME by monitoring the camshaft's position. The data from this sensor is key to optimizing ignition timing and ensuring smooth engine performance. Often referred to as the CMP sensor, this component is crucial for the overall functionality of the powertrain. A failing camshaft position sensor can cause a range of issues, including engine stumbling, hesitation during acceleration, power loss, and even starting difficulties or complete failure to start.
